Hereditary chorea. Chorea, or (rarely) choreia, (/ k ə ˈ r i ə /) is an abnormal involuntary movement disorder, characterized by quick movements of the hands or feet.It is one of a group of neurological disorders called dyskinesias.
Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized. [3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying ...
The age at onset is between 1 and 20 years old. The attacks of involuntary movements last less than one minute and have a known trigger, usually a sudden voluntary movement. For example, if a PKD patient stands up or begins walking after being sedentary for a period of time, or a person goes from a walk to a run, it can trigger an attack.
Correlations between the causes of young-onset Parkinson's disease and PED may be due to a similar problem, specifically a mutation of a potassium channel gene on chromosome 1. [ 4 ] The pathogenesis of PED has also been linked to mutations in the GLUT1 glucose transporter which can result in transient energy deficits in the basal ganglia. [ 2 ]
Hyperkinetic movement disorders refer to dyskinesia, or excessive, often repetitive, involuntary movements that intrude upon the normal flow of motor activity. Hypokinetic movement disorders fall into one of four subcategories: akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity.
Dyskinetic cerebral palsy could have multiple causes. The majority of the children are born at term and experience perinatal adverse events which can be supported by neuroimaging. Possible causes are perinatal hypoxic-ischaemia and neonatal shock in children born at term or near term.
Huntington's disease (HD), also known as Huntington's chorea, is an incurable neurodegenerative disease [7] that is mostly inherited. [8] The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities. [9] [1] A general lack of coordination and an unsteady gait often follow. [2]
Sydenham's chorea is a disorder characterized by rapid, uncoordinated jerking movements primarily affecting the face, hands and feet. [14] It is a result of an autoimmune response that occurs following infection by group A β-hemolytic streptococci (GABHS) [ 15 ] that destroys cells in the corpus striatum of the basal ganglia .
